{"id":"CVE-2023-30606","state":"PUBLISHED","title":"Multisite denial of service through unsanitized dynamic dispatch to SiteSetting in Discourse","description":"Discourse is an open source platform for community discussion. In affected versions a user logged as an administrator can call arbitrary methods on the `SiteSetting` class, notably `#clear_cache!` and `#notify_changed!`, which when done on a multisite instance, can affect the entire cluster resulting in a denial of service. Users not running in multisite environments are not affected. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. Users are advised to upgrade. There are no known workarounds for this vulnerability.","publishedAt":"2023-04-18T21:36:08.683Z","updatedAt":"2025-02-06T16:37:26.242Z","severity":{"score":4.2,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["discourse discourse"],"affected":[{"vendor":"discourse","product":"discourse","versions":[{"version":"stable: < 3.0.2","status":"affected"},{"version":"beta: < 3.1.0.beta3","status":"affected"}]}],"references":["https://github.com/discourse/discourse/security/advisories/GHSA-jj93-w3mv-3jvv"],"weaknesses":["CWE-732"],"ingestedAt":"2026-10-29T20:05:52.290Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/30xxx/CVE-2023-30606.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-30606","state":"PUBLISHED","datePublished":"2023-04-18T21:36:08.683Z","dateUpdated":"2025-02-06T16:37:26.242Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-04-13T13:25:18.830Z"},"containers":{"cna":{"title":"Multisite denial of service through unsanitized dynamic dispatch to SiteSetting in Discourse","descriptions":[{"lang":"en","value":"Discourse is an open source platform for community discussion.
